LOINC long common name : Toe brachial index - left;
LOINC short name : TBI left;
LOINC description : The reading is derived in order to determine the severity of peripheral arterial disease
present in a lower extremity. The test is performed using a small blood pressure cuff
that is fitted around a toe along with a photoplethysmograph (PPG) infrared light
sensor. The resultant toe brachial index (TBI) is generated using the systolic blood
pressure readings from the arm and toe.;
